Complex-1 is a modular synthesizer from Reason Studios, bringing the quirks, freedom and sonic depth of modular synthesis to to your Reason Rack.

If you’re a seasoned modular synth enthusiast, you can dive right in. If this kind of synth is new to you, load up any of the included patches to get you going, and start your sonic exploration there. Nothing can break, and if things go weird (like, in a bad way), and there’s the undo button to your rescue. Boasting a 4x oversampled synthesis engine, a freely routable signal and modulation path and a sound like nothing else, Complex-1 is a synth lover’s dream machine.
